This protective case is really very stable, so they are almost opened successfully defends against. Who likes to have long fingernails, you will lose in this box. I am also the very high weight but scared at this size. Who needs to pay attention to the total weight will remain safe in the small plastic Cases of cards. Properly secure remain the SD card with me not fixed in its holder. But more than three stars for stable storage, I would not forgive. For CF cards, the shutter is better resolved and overall better and the higher weight does not bother me because that way.
